Abstract: A system and method for verifying computation output using computer hardware are provided. Instances of computation are generated and processed on hardware-based processors. As instances of computation are processed, each instance of computation receives a load accessible to other instances of computation. Instances of output are generated by processing the instances of computation. The instances of output are verified against each other in a hardware based processor to ensure accuracy of the output.

Abstract: In some embodiments, a method for improving reliability in a processor is provided. The method can include replicating input data for first and second lanes of a processor, the first and second lanes being located in a same cluster of the processor and the first and second lanes each generating a respective value associated with an instruction to be executed in the respective lane, and responsive to a determination that the generated values do not match, providing an indication that the generated values do not match.

Abstract: A system and method for optimizing redundant output verification, are provided. A hardware-based store fingerprint buffer receives multiple instances of output from multiple instances of computation. The store fingerprint buffer generates a signature from the content included in the multiple instances of output. When a barrier is reached, the store fingerprint buffer uses the signature to verify the content is error-free.
